SPECIFICATION forming part of Letters IPatent No. 654,488, dated July24, 1909. Application. filed September 21, 1899. Serial No. 731,170. (N0model.)

To aZZ whom it may concern: I Be it known that 1, Bauer PETERSON, ofDassel, Meeker county, Minnesota, have invented certain new and usefulImprovements specification.

The invention relates to devices used in connection with heating-drums;and the object of the invention is to provide means tually cleaned ofthe accumulated soot and dust.

The invention consists generally in various constructions andcombinations, all as hereout in the claim.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of a heating-drum embodying my inven- Fig. 2 is avertical sectional view on the line y y of Fig. 1. Fig. 3 is ahorizontal section on the line a: 00 of Fig. 2.

In the drawings, 2 and 3 represent, respectively, the opposite heads ofa drum, having the heads are preferablyinclined or converge, and theinner ends of said heads are closed by partitions or walls 6 and 7. Aseries of holes are provided in said walls 6 and ,7, ar-

the heads, and said holes'are connected bya series of flues 8,communicating with theinterior of the heads 2 and 3 and through whichthe smoke and products of combustion pass Within said smoke-fines 8 Iprefer to arrange a series of smaller flues 9, whose ends extend throughthe heads 2 and 3and are secured to the outside inclined walls of thesame, causing said open air. The drum is designed particularly to beinserted between two sections of stovepipe, and as the smoke andproducts of combustion enter the end of the dr11m say up through thefines 8, heating the air-flues 9, through which a current of cool air isconstantly passing to be heated and discharged the room.

concentrically,with but a short space between them, it follows that thesoot will gather upon the walls of said flues and after a time seriously interfere with the heating of the same and in consequencedecreasethe heating capacity of the drum. I therefore provide a seriesof rods 10, one for each hot-air flue, adapted to slide up and down inholes in the top of the drumhead and in the space between said flues andhaving their inner ends bent at a right angle to the main portion of therods and looped around the dues 9, the loops being sufficientlyloose topermit the rods to slide freely up and down Within the space betweensaid fiues and scrapethe walls of the same clear of all accumulated sootand dirt, whichfalling upon the inclined lower-end "of the drum willslide down into the smoke-pipe and thence to the fire. Instead offorminga loop at the bottom of the rod I may provide a ring upon eachflue, connecting the same withithe vertically-moving rod. 1

With the aid of the cleaning de vice,asabove set forth,the hot-airflu'esof the heating drum may be kept thoroughly clean from soot and otherforeign material without the necessity of taking the drum apart, and inthis way the highest degree of efficiency of a heating drum may beobtained at all times.

In various ways the detailsof the device may be modified. Hence I do notwish to be confined to the particular construction herein described. 1

Having thus described my invention, I claim as new and desire to securebyLetters Patent I A heating-drum, comprising heads 2 'and 3 having,respectively, smoke inlet and outlet openings 4 and 5, the walls formingthe outer ends of said heads being inclined toward their respectiveopenings, a series of smoke-flues 8 connecting said heads, a series ofair-flues 9 having open ends extending through said heads and providedone within each of said smoke-fines and concentric therewith and spacedfrom the walls of the same forming a series of annular smoke-passagesbetween 'theinolined walls of said heads through the 10 said heads, anda series of rods 10 provided opening therein, substantially asdescribed. one within each of said smoke-passages, the In witnesswhereof I have hereunto set my outaeril enis ofdstalild rods projgetlingtlrirouglci hand this 16th day of September, A.
